  • Methods of making transportation fuel
    Patent number: 8151880
    Abstract: A method for producing alkylated hydrocarbons is disclosed. Formation fluid is produced from a subsurface in situ heat treatment process. The formation fluid is separated to produce a liquid stream and a first gas stream. The first gas stream includes olefins. The liquid stream is fractionated to produce at least a second gas stream including hydrocarbons having a carbon number of at least 3. The first gas stream and the second gas stream are introduced into an alkylation unit to produce alkylated hydrocarbons. At least a portion of the olefins in the first gas stream enhance alkylation. The alkylated hydrocarbons may be blended with one or more components to produce transportation fuel.
    Type: Grant
    Filed: December 9, 2010
    Date of Patent: April 10, 2012
    Assignee: Shell Oil Company
    Inventors: Augustinus Wilhelmus Maria Roes, Weijian Mo, Michel Serge Marie Muylle, Remco Hugo Mandema, Vijay Nair
